Hydrology and Hydrogeology

Recognition of hydrological conditions and hydrological feeding system of the area
Statistical analysis of the time series of hydro-meteorological data will enable for initial assessment of hydrological situation in the Jegrznia river – Woźnawiejski Canal watershed, where the Red Bog reserve is located. Additionally, devices (Diver type) for automatic recording of ground water level will be installed at selected locations in the area of the Red Bog reserve. The obtained data will allow for characterizing a dynamic of peatland moisture level at selected, specific locations. Present condition of the surface water network will be determined based on the complex field investigations including among others: water discharge and longitudinal slope measurements and delimitation of the boundary of sub-catchments. Recognition of quality component in waters feeding the area, including determination of factors (areas) constituting quality of recharging waters, will be done using statistical methods based on results of quality measurements and laboratory analyses of ground and surface waters, collected in the first two years of the project. The results of quality and quantity measurements and statistical analysis will allow for recognition of sources and directions of peatland feeding. Identification of hydrogeological parameters and filtration characteristics will enable calibration of groundwater model and determination of groundwater component magnitude in recharging of the area, and as consequence for determination of dynamic of groundwater recharge magnitude.

Characteristic of integral water relations determining moisture conditions of the Red Bog
Development of the hydrological balance model will contain following steps: a model choice, parameters identification and model’s calibration based on the historical data. Verification of the model will be done based on results of hydro-meteorological measurements conducted during the first two years of the project. Analysis of hydrological changes as result of historical and predicted by vegetation team changes in vegetation structure will be done by simulation of the water balance model. Assessment of tendency of hydrological conditions will contain a summary and generalization of modelling results in aspect of peat forming processes and presence of required vegetation communities.
